I'm having a very interesting conversation (for me, at least) with Richard Chappell over at Philosophy, et cetera about his post on species and cognitive enhancement. You may notice that my position flip-flops. I take that as a good sign. I think flip-flopping when one contemplates a difficult philosophical problem or puzzle often is an indication of critical engagement and learning.
I must, of course, contrast flip-flopping with waffling, which I take to be when one flip-flops rapidly for the purposes of obfuscation, to avoid responsibility for having taken any position at all. Waffling is when one tries to have one's pancake and eat it, too.
